Sciaenuropsis turneri was a beryciform-grade teleost represented by three-dimensional London Clay skulls. Recent imaging of specimens with otoliths still preserved inside the cranium has made the species especially important, because it directly connects a body-fossil taxon with an otolith morphology that had previously been classified independently.

The skull has a strongly ornamented opercular region and a distinctive raised node on the roof, while the eye was supported by an ossified sclerotic ring. Its exact ecological niche is not securely known; a carnivorous role is plausible from its acanthomorph construction, but the more significant evidence lies in the rare association of skull and ear stones, which helps reconcile two traditionally separate fossil records.
